WINDING MECHANISM.

Specification of Letters Patent.

Patented July 14:, 1914.

Application filed February 16, 191-4. Serial No. 818,841.

To all whom it may concern Be it known that I, EMORY J. Lirrs, a citizen of the United States, residing at borough of Fountain Hill, in the county of'Lehigh and State of Pennsylvania, have invented certain new and useful Improvements in Winding Mechanisms, of which the following is a specification.

This invention relates to wound packageforming. mechanism of the general class in which one of the two members afiording an axial support for the package and a guide for the thread or yarn rotates around the axis of the supporting member to accomplish the winding, one reciprocates longitudinally of said axis to lay the windings spirally around said axis, and one is shiftedlongitudinally of said axis, due to im pact of the thread-guide member at intervals with the package, to advance the point of winding from time to time, so that the windings come to be disposed in the finished package generally as conical layers. Where such packages are wound on wooden or similarv quills, means is afforded by the en largement at the quill butt for supporting the windings at the butt of the package; but where they are formed on paper or similar tubes having no enlargement at the butt to support. the windings means have to be provided inthe winding machine for s0 controlling the package as to make the same as well as its. point or free end tapered, thereby to prevent-its coils at the butt loosening and falling away in handling. Such means have heretofore been more or less complicated and cumbersome; and it is therefore theobjectsame. I accomplish this object, briefly stated, by providing the support around which the windings are coiled and in the portion thereof surrounded by the buttcoils of the package with a lateral offset, formed usually to converge forwardly toward the/axis of winding. In the adaptat-ions herein shown and described this offset serves to displace laterally, or to maindisplaced, a part of the butt of the cop-tube as a lateral offset thereof when the tube is forced on the spindle; but it shouldv be understood that the invention is not limited'to the offset having this supplemental function, the essential feature being a lateral offset on the support around which the windings are formed and in the the winding of the butt of of this invention to simplify the part thereof surrounded by the butt-windings, whereby means is afforded by which, without complicated mechanism, the building of the heel or butt of a cop or other wound package can be started without the instrumentality of the conical enlargement characteristic of a quill.

In the accompanying drawings, Figure 1 shows the essential elements of a quilling machine, which is chosen as illustrative of the class of winding machines above referred to as that to which my invention relates, the spindle thereof having applied thereto an attachment constituting one form of the aforesaid offset; Fig. 2 shows the said attachment in side elevation and the spindle in dotted outline; Fig. 3 is a longitudinal sectional view through a wound package formed on a spindle in accordance with this invention, and showing the Shape of the package as formed; Fig. a is a sectional view on the line wm of Fig. 3; Fig. 5 is a longitudinal sectional view of the package, showing the shape it is made to assume for use; Fig. 6 is a sectional view on the line y y of Fig. 5; and, Fig. 7 shows a modification other form of the ofi'set.

In Fig. 1, in a suitable frame or support a, are shown the spindle member Z) and the threadrguide member generally indicatedloy c and including the thread-guide proper d and the rotary wheel carrying shaft 6, the wheel whereof is indicated by e, the thread-guide proper d and the shaft 0 having a suitable coupling means f. In this particular form of winding mechanism, the spindle member rotates (on its own axis), 9 being a suitable clutch member for. rotating it; and the threadguide member reoiprocates, of progressively shifting, parallel with the axis of the spindle, the reciprocating being effected by an oscillating fork h engaging threading on the shaft 6 and the shifting being accomplished by the wheel 6 impinging from time to time against the wound package and so turning shaft e in the fork, all with the effect in the regular operation of the mechanism of progressively advancing the thread-guide member parallel with reclprocatlng the spindle while it is through a distance representing but a part of the length of the package being formed.

In accordance with my invention, as

shown in Fig. 1 and 2, I apply to the spinof my invention, illustrating anand is susceptible I 20 incidentally dle member 6 an attachment including a collar 1', adapted to be slipped over the spindle and bear against its shoulder y and having a set-screw 7a to removably secure it in place, and, projecting forwardly from said collar, an elongated rib Z which lies flat against one side of the spindle and has its outer or actmg face in converging forwardly toward the splndle axls. Prefer- 10 ably, the spindle is cut away somewhat on the side thereof opposite to the rib Z, as in dicated at n in Fig. 2; this, however, is not indispensable.

Then a cop tube A is now slipped on the spindle, its butt-end is caused, by inclined surface m of the offset afforded by saidattachment, to be displaced or offset laterally with respect to the spindle axis, in the particular adaptation being referred to being stretched into substantially ovoid shape in cross-section as shown in Figs. 3 and 4-.

On the mechanism being now set in opera tion, on the first reciprocating thrust of the thread-guide member to the right in Fig.

1 its wheel 6 will impinge against the laterally offset or high part of the coptubebutt, receiving a rotary impulse that will advance said thread-guide member to the left relatively to the fork h. In the ensuing reciprocations of the thread-guide member a layer or layers of windings of thread or yarn will be wound around the butt pOIt of the .coptube. Eventually on one of the reciprocations of the thread-guide member to the right the wheel 0 will impinge against the windings where maintained relatively offset by the offset portion of the coptube, receiving another rotary impulse that 40 will again cause the advancement of the thread-guide member to the left; and so on, the windings being progressively advanced along the butt portion of the spindle and s0 building up into the desired conical heel or butt of the wound package.

The package will have, when completed,

- approximately the form shown in Figs. 8

and 4 in which, in. any cross-section through the portion thereof where the offset affected the windings, the package appears ovoid in contour, this shape being most pronounced at the extreme end of the cop butt and gradually approaching the circular toward the cross section where the taperlng heel merges into; the cylindrical body. But the heel of the cop may be readily made to assume the form of a perfect cone as soon as the package is slipped on a spindle (compare Figs. 5 and 6) and the bore. of the package is thereby straightened out.

- The ofiset may be producedin other ways, for instance, as shown in Fig. 7 where the spindle b has an angularportion b which,

as to its cop-tube-butt receiving part b what I claim as new and desire to secure by.
